D490A Φ190-220mm Integrated Dth Surface Drilling Rig For Mining

The RuiXin D490A features a unique double-boom and dual-feed beam design, with an overall weight of 38 tons. Equipped with a high-power engine and a 9-meter-long drill pipe configuration, it is capable of drilling holes with a diameter of over 200mm—meeting the demands of large-hole drilling scenarios such as medium and large-scale mining or deep foundation construction.Compared to traditional tower drilling rigs, this model offers a distinct flexibility advantage: its compact structural layout and optimized maneuvering performance allow it to adapt more easily to complex on-site conditions, including uneven terrain or limited operating spaces. Additionally, a jib boom and hydraulic winch are mounted on top of the feed beam, providing a stable and safe solution for lifting, transferring, and installing drilling tools—effectively reducing manual handling risks and improving operational efficiency.
